Quantum physics and the theory of relativity have shaken our conception of reality. They have made us realize that the universe is not as we perceive it. Religion and philosophy have so far failed to adapt our view of the world on the basis of these findings. Thus, together with the reader, the author sets out to clarify the fundamental questions of life. He skillfully juxtaposes convincing answers from different fields of knowledge. Scientific chapters about the world of quantum objects, space and time, or the origin and evolution of the universe stand in stark contrast to chapters about scientifically unexplainable events such as miracles, spiritualistic phenomena, findings about life after death, and reincarnation. In addition, the author discusses the atheistic worldview. The scientific sections are easily understandable, especially since they are, to a large extent, free of technical terms and formulas. In the religious chapters, the author draws parallels between ideas from all religions (especially Hinduism, Buddhism, and Taoism) and scientific findings. Descriptions of the God-experiences of spiritual masters from all times, cultures, and religions as well as personal anecdotes and stories imagined by the author provide manifold paradigm shifts in the detailed consideration of one and the same thing: the ultimate reason of our existence and the meaning of life.
